BaZi Charting - Step by Step

Learning BaZi starts with a correct chart: year from solar terms, month from commanding season, day from jiazi, hour from double-hours—any step wrong skews Ten Gods and strength. Below each pillar in order; if birth involved time zone, DST, or longitude, normalize first then convert.

Four pillars split birth time into Year, Month, Day, Hour—one stem and one branch each, eight characters total:

• Year pillar: roots, ancestors, broad environment; early life often echoes it
• Month pillar: parents, siblings, mid-life career and family atmosphere
• Day pillar: core—day stem is “me,” whole chart revolves around it
• Hour pillar: children, descendants, later life

Traditional casting does not use lunar New Year or January 1 for year/month—it uses Twenty-Four Solar Terms—different from many wall calendars but BaZi’s heaven-timing base.

Four-pillar method

Prepare accurate birth data—prefer Gregorian year/month/day/hour, 24-hour clock from hospital or official records. Lunar-only dates must convert to Gregorian; note sex (affects major luck forward/backward).

Year pillar

BaZi “year” is not January 1 or lunar New Year—it is Lichun (Start of Spring).

• On or after Lichun → that year’s stem-branch
• Before Lichun → previous year’s stem-branch

Worldwide, use local Lichun moment—usually Feb 3–5; check almanac.

Month pillar

Most critical and most error-prone. Month follows solar terms—each term starts a new month; month branch fixed, e.g.:

• Lichun to Awakening of Insects → first month (Yin)
• Awakening of Insects to Pure Brightness → second month (Mao)
• Pure Brightness to Start of Summer → third month (Chen)
• Start of Summer to Grain in Ear → fourth month (Si)

…and so on. Hai month (Start of Winter to Major Snow), Zi (Major Snow to Minor Cold), Chou (Minor Cold to next Lichun) are months 11–12. Month stem from Five Tigers (wuhu dun) by year stem. Month pillar drives elemental strength—do not map from lunar month alone.

Day pillar

Sixty jiazi day count—modern charts use reliable algorithms. Day stem is “me”—chart core.

Hour pillar

Map clock to twelve double-hours:

• Zi (23:00–01:00)
• Chou (01:00–03:00)
• Yin (03:00–05:00)
  …

Zi spans two calendar days—distinguish late Zi vs early Zi and whether the day has rolled.

Beginners often use Gregorian or lunar month for month branch—month wrong, all downstream analysis wrong. Lock solar terms and logic clears up.

Global births

Logic is the same worldwide; watch time zones and DST—restore standard time before casting where DST applied.

Near boundaries (≈07:00, 11:00, 15:00, 23:00)—minutes can change hour pillar and temperament/luck reads. Record time precisely; recheck birth certificate with family if possible.

True Solar Time

After four pillars look solid, for classical precision apply True Solar Time.

Ancients used sundial (true solar); modern clocks use mean solar (standard time). Difference is minutes daily—critical at hour edges.

Adjust when:

• birth time sits on double-hour boundary
• deeper analysis needed

Convert clock time to that day’s true solar, then assign hour pillar—minutes near boundary can change pillar; be careful.

With eight characters set, continue stems/branches, Ten Gods, or strong/weak and useful god. To cast with modern analysis, visit Ming Ming Guan Zhi BaZi for a free trial.
